This operation is continued until the gun is filled to a desired point or capacity, and is then removed from the nozzle. In order to prevent ior= eign matter entering the nozzle when not in use, provision is made of a cap 36 which may be inserted over the end of the nozzle. 7

A hand grip 35 is mounted upon the upper end of the rack bar, for the purpose of returning the piston to its uppermost position. The handle also serves as a means for transporting the container from one place to another.

Inasmuch as grease guns may vary as to the diameter of the barrel 4 and I have shown modifications of adapters which may be used with the discharge nozzle. In Figure 4, I have shown an adapter 36 which includes a clamp collar 37 and a reduced nipple 38.

The adapter 36 may be clamped to the upper end of'the discharge nozzle as will be apparent. In Figure 5, the upper end of the nozzle 32 is screwthreaded as at 39, and the interior of the collar 69 of' the adapter is similarly threaded, and through these means the adapter may be attached.

' It will be obvious that the filler device may be employed in other situations, such as the filling of caulking guns and the like.

While I-have shown and described a preferred construction, this is by way of illustration only, and I consider as my own all such variations in structure as fairly fall within the scope of the appended claims.

1. In combination, a container for grease or the like having an open top, a piston slidably mounted in the container, a yoke detachably portion thereof, in Figures araaeec mounted upon the container, said yoke extending above and across the container and having a slot medially thereof, a rack bar on the piston and extended through the slot of the yoke, a standard having an inclined slot, an operating lever including a pin pivotally mounted in the 7 slot of the standard, a pawl on the operating lever cooperable with the teeth of the rack bar to eirect downward movement of the piston, means on the lever engageable with the standard to prevent limited downward movement of the lever and a nozzle on the pistonin communication with acontainer, said nozzle extending upwardly above the piston and of a length greater than the depth of the container.

2. In combination, a container for grease or the like having an open top, a piston slidably' mounted in the container, a yoke member, said yoke comprising a split" ring circumscribing the container and having securing means, the yoke having upstanding legs and a transverse member,

said transverse member having a slot medially thereof, a rack bar on the piston and extended through the slot of the transverse member, an upright standard on the transverse member, the standard having an inclined slot, an operating lever pivotally mounted in the inclined slot, a pawl on the lever cooperable' with the teeth of the rack bar, for efiecting downward movement of the piston, hand grip means on the rack bar for returning the piston toraised position, means on the lever engageable with the standard to limit downward movement of the lever, and a nozzle on the upper side of the piston in communication with the container, said nozzle extending upwardly above the piston and of a length reater than the depth of the container. 1
